OSM UK Alcohol Outlet Counts and Quality Index
No full textThis data deposit contains two things. First, there is the replication data behind the paper 'OpenStreetMap data for alcohol research: Reliability assessment and quality indicators'. Second, there are UK wide, postcode sector level counts of alcohol points of sale, based on calculations from OpenStreetMap. These include calculations of a quality index which seeks to measure the quality of OSM data in a given area. See the paper for further details, or contact Jonathan Bright.

Going Beyond Counting First Authors in Author Co-citation Analysis
Get PDFThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
Variations on the Author
Get PDF“Variations on the Author” discusses two of Eduardo Coutinho’s recent films (Um Dia na Vida, from 2010, and Últimas Conversas, posthumously released in 2015) and their contribution to the general question of documentary authorship. The director’s filmography is characterized by a consistent yet self-effacing form of authorial self-inscription: Coutinho often features as an interviewer that rather than express opinions propels discourses; an interviewer that is good at listening. This mode of self-inscription characterizes him as an author who is not expressive but who is nonetheless markedly present on the screen. In Um Dia na Vida, however, Coutinho is completely absent form the image, while Últimas Conversas, on the contrary, includes a confessional prologue that moves the director from the margins to the center of his films. This article examines the ways in which these works stand out in the filmography of a director who offers new insights into the notion of cinematic authorship
Appropriate Similarity Measures for Author Cocitation Analysis
Get PDFWe provide a number of new insights into the methodological discussion about author cocitation analysis. We first argue that the use of the Pearson correlation for measuring the similarity between authors’ cocitation profiles is not very satisfactory. We then discuss what kind of similarity measures may be used as an alternative to the Pearson correlation. We consider three similarity measures in particular. One is the well-known cosine. The other two similarity measures have not been used before in the bibliometric literature. Finally, we show by means of an example that our findings have a high practical relevance.information science;Pearson correlation;cosine;similarity measure;author cocitation analysis
Dispelling the Myths Behind First-author Citation Counts
Get PDFWe conducted a full-scale evaluative citation analysis study of scholars in the XML research field to explore just how different from each other author rankings resulting from different citation counting methods actually are, and to demonstrate the capability of emerging data and tools on the Web in supporting more realistic citation counting methods. Our results contest some common arguments for the continued
use of first-author citation counts in the evaluation of scholars, such as high correlations between author rankings by first-author citation counts and other citation
counting methods, and high costs of using more realistic citation counting methods that are not well-supported by the ISI databases. It is argued that increasingly available digital full text research papers make it possible for citation analysis studies to go beyond what the ISI databases have directly supported and to employ more
sophisticated methods
Leveraging the left: examining Russian left-leaning provocation on Instagram in 2020
Get PDFPursuing a strategy of provocation, the Russian government has leveraged proxy
media accounts on social media to disseminate strong, often-fringe political stances
within a broader left-leaning ecosystem. While these proxy voices, termed “the
Fringenet,” author such narratives, their posts are spread by “fellow travellers,”
accounts that wittingly or unwittingly amplify Russian provocation efforts. Beyond
their symbolic importance, it remains unclear whether reposts have any significance,
such as generating follower growth for Fringenet accounts.
This thesis seeks to tackle this question with a series of theoretical and methodological contributions to the literature. By drawing together a novel dataset of Instagram reposts and posts by Russian provocation accounts, social network theory,
and time-series modelling, I examine how three Fringenet media channels built their
amplification network of followers. To determine whether reposts influence follower
growth, I use vector autoregression models paired with Granger causality tests and
impulse response functions to explore the time-ordered relationship between reposts
and follower growth. Further, to examine who is reposting Russian provocation content and on what topics, I conduct an intensive manual coding process of account
types (N = 1,870) and posts and reposts (N = 4,050).
My results reveal both a top-down broadcast model – where influential users like
private companies and influencers generated follower growth for Fringenet accounts
by signalling to their followers that these accounts were authentic and credible – and
a bottom-up social contagion model – where the sheer number of users reposting
Fringenet accounts led to follower growth by building a critical mass. Furthermore,
my descriptive analyses highlight that reposts were frequently shared by fellow independent and alternative news accounts as well as authentic private companies
and activists and civil society groups. Finally, I find reposts and posts converging
around topics such as Black Lives Matter, climate change, and COVID-19.
Given recent decisions to label Russian media accounts as state-run, the substantive and methodological contributions of this thesis are relevant for the academic community and for policymakers. For the academic community, this thesis
demonstrates the need for a multiplayer analysis when studying Russian information operations. For policymakers, this thesis highlights the drawbacks of a focus
solely on countering disinformation through fact-checking, which overlooks the way
Russian accounts are not merely passive purveyors of false information but rather
active participants fanning the flames of ongoing political discourse
koamabayili/VECTRON-author-checklist: VECTRON author checklist
No full textWe have done our best to complete the author checklist relating to the use of animals in the hut study. Note that the objective for the hut study was to evaluate the IRS treatment applications for residual efficacy against Anopheles mosquitoes, including the local An. coluzzii mosquito population. Cows were only used to attract mosquitoes into the huts and no tests were carried out directly on the cows. The author checklist is intended for use with studies where experiments are carried out on animals, which is why we have had such difficulty in completing this for the hut study, as many of the questions do not relate to how the cows were used
